2. Security notes

Device may only be disposed in a professional manner !

The installation and commissioning should only be carried out by trained personnel.
Check the following points before commissioning:
– that the maximum values for all the connections are not exceeded, see "Technical data"

section,
– that the connection wires are not damaged, and that they are not live during wiring,
– that the power flow direction and the phase rotation are correct.
The instrument must be taken out of service if safe operation is no longer possible (e.g. visible

damage). In this case, all the connections must be switched off. The instrument must be
returned to the factory or to an authorized service dealer.

It is forbidden to open the housing and to make modifications to the instrument. The instrument
is not equipped with an integrated circuit breaker. During installation check that a labeled switch
is installed and that it can easily be reached by the operators.

Unauthorized repair or alteration of the unit invalidates the warranty.

3. Device overview

3.1 Brief description

The APLUS is a comprehens ive instrument for the u niversal measurem ent, monitoring and power quality
analysis in power systems. The device can be adapted fast and easily to the meas urement task by means
of the CB-Manager software. T he universal measurement s ystem of the device may be used directl y for
any power system , from single ph ase up to 4-wire unbalanced netw orks, without hardware m odifications.
Independent of measurement task and outer influences always the same high performance is achieved.

Using additional, opt ional com ponents the opportunities of the A

PLUS m ay be extended . You may choose

from I/O extens ions, communic ation interf aces or data log ger. The nam eplate on the d evice gives f urther
details about the present version.

The version with top-ha t rail adapter instead of the display has th e same dimens ions and connec tions as
the version with display and supports the same options.

7/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

3.2 Possible modes of operation

The APLUS can cover a wide range of possible input ranges without any hardware variance. The adaption
to the input signal is performed by means of variable amplifying levels for current and voltage inputs.
Depending on the application it makes sense to fix these levels by means of the configuration or to let
them stay variable to achieve a maximum accuracy during measurement. The differentiation, if the
amplifying remains constant or is adapted to the present value, is done during the definition of the input
configuration by means of the parameter "auto-scaling".

The disadvantage of auto-scaling is t hat whe n an amplifying level needs to be changed, a settling time of
at least one cycle of the power frequency must be allowed until the signals have stabilized again. During
this short time the measurement results remain frozen.

Continuous measurement

An absolute uninterrupted measurement of all quantities assumes that auto-scaling is deactivated for both
voltage and current inputs.

Metering

The uncertainty of the active energy meters of the A

PLUS is given with class 0.5S. To fulfill the high

requirements of the underlying meter standard EN 62053-22 also small currents have to be measured
very accurate. To do so, auto-scaling must be activated for current inputs. For metering applications the
system voltage is assumed to be quite constant, nominal value acc. standard, wherefore auto-scaling for
voltages is not required. The subsequent example shows an appropriate configuration, which also
conforms to the factory setting of the device.

Dynamic monitoring of limit values

An important criterion when monitoring the quality of the supply voltage is the possibility to detect short
sags of the system voltage. To be able to follow the progress of the voltage auto-scaling of the voltage
inputs should be deactivated. Thereby you have to consider that a possible swell of the voltage may be
detected only up to the configured overriding (20% of rated voltage in the above example), because the
switching of the measurement range is locked in both directions.

This applies analogously to all quantities of the system, whose progress should be monitored. For power
quantities the voltage amplification as well as the current amplification is influenced. However, which basic
quantities may vary how much can differ from application to application.

8/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

3.3 Monitoring and alarming

The logic module integrated in the APLUS is a powerful feature to monitor critical situations without delay
on device side. By implementing this local intelligence a safe monitoring can be realized which is
independent of the readiness of the control system.

3.3.1 Alarming concept

How alarms are handled is decided during the configuration of the device. For that in the logic module you
can define if LED's are used for alarm state display and how resp. when a possibly activated action, such
as the switching of a relay, will be reset. These configuration parameters are highlighted in yellow in the
following chart.

► Acknowledgment: This procedure affects the state of the LED only
If an alarm state is visualized via LED, its occurence must be acknowledged v ia displ a y (see:

Acknowledgment of alarms via display), no matter if it is still active (fast flashing) or has dropped-out

already (slow flashing). By acknowledging an alarm, only the flashing of the LED stops, but a reset of the
alarm action is performed only if the display is configured as a possible source for alarm reset.

Acknowledgment is not required if "acknowledgement of alarm LEDs required" in the
logic module configuration is not selected.

► Alarm reset : This procedure affects the states of the follow-up action and the LEDs
If an alarm state occurs a follow-up action (e.g. the switching of a relay) can be triggered. This follow-up

action is normally reset as soon as the alarm condition no longer exists. But the alarm handling may be
configured as well in a way that only by means of an alarm reset the subsequ ent o perati on is withdra w n.
This way an alarm remains stored until a reset is performed, even if the alarm situation no longer exists.
Possible sources for an alarm reset are the display, a digital input, another logical state of the logic
module or a command via the bus interface.

Hint: If an alarm is reset, the alarm state visualized via LED is acknowledged at the same time.

On the next page some signal flow examples are shown.

3.3.2 Logic components

The logic outputs are calculated via a two level logical combination of states, which are present at the
inputs. Usable components are AND, OR and XOR gates as well as their inversions NAND, NOR and
XNOR.

The principal function of the logical gates is given in the following table, for simplicity shown for gates with
two inputs only.

3.3.3 Limit values

States of limit values are the most important input quantities of the logic module. Depending on the
application, limits either monitor the exceeding of a given value (upper limit) or the fall below a given value
(lower limit). Limits are defined by means of two parameters, the limit for the ON and the limit for the OFF
state. The hysteresis is the difference between these two values.

Upper limit: The limit for ON state (

L.On

) is higher than the limit for the OFF state (

L.OFF

)

Limit for OFF state

Limit state

0

1

Limit for ON state

► The state 1 (true) results if the limit for ON state is exceeded. It remains until the value falls below the

limit for OFF state again.

► The state 0 (false) results if the limit for ON state is not yet reached or if, following the activation of the

limit value, the value falls below the limit for OFF state again.

Lower limit: The limit for ON state (

L.On

) is smaller than the limit for OFF state (

L.OFF

)

Limit for ON state

Limit state

0

1

Limit for OFF state

► The state 1 (true) results if the value falls below the limit for ON state. It remains until the value

exceeds the limit for OFF state again.

► The state 0 (false) results if the value is higher than the limit for ON state or if, following the activation

of the limit value, the value exceeds the limit for OFF state again.

If for a limit value the limit for ON state and the limit for OFF state are configured to
the same value, it will be treated as an upper limit value with a hysteresis of 0%.

Limit values may be used to control the running of operating hour counters. As long as the limit values
are fulfilled (logical 1) the operating hour counters keep on running. Not only operating times may be
measured, but e.g. time under overload condition (additional stress) as well.

12/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

3.3.4 Sequence of evaluation

The evaluation of the logic module is performed from top to bottom and from left to right:

1. Y1, Y2, Y3, Y4

2. Z1, Z2, Z3, Z4

3. D1, D2, D3, D4

4. A1, A2, A3, A4

► The evaluation is performed once each cycle of the power frequency, e.g. every 20ms at 50Hz. But the

time between two evaluations will never be longer than 25ms.

► If the logical states Y1...Y4, Z1...Z4, D1...D4 and A 1...A 4 are used as inputs, their changed states will

be included in the evaluation of the next interval

► Exception: In the first evaluation level the state of previous logical functions may be used as input

without delay, e.g. the state Y1 for the logical functions with output Y2, Y3 or Y4.

13/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

3.4 Free Modbus image

Accessing measured data of a Modbus device often needs some special effort, if the interesting
measurements are stored in different, non continuous register areas. This way multiple telegrams must be
sent to the device to read all data. This needs time and it's very likely, that the measurements don't
originate from the same measurement cycle.

A free assembly of the data to read helps a lot. The A

PLUS supports, along with the still available classical

Modbus image with thousands of registers, the facility to assemble two different images, which may be
read with one telegram only. These freely assembled images are refreshed after each measurement cycle
and therefore always provide the most present values.

The free float image

Up to 60 instantaneous, mean, unbalance or THD/TDD values may be arranged in any sequence on the
register addresses 41840-41958. All of these values are floating point numbers, which allocate 2 registers
per value. Meter values are not possible because they have another format.

The free integer image

Some older control systems are not able to handle float values. To make it possible to work with the data
of the device up to 20 16-Bit integer values can be derived from the existing measurement values. These
values will then be stored in the free Modbus image (register 41800 up to 41819) as integer values with
selectable range of values.

Example: Current transformer 100/5A, measurement current phase 1, over range 20%

► The reference value is 120A (maximum measurable current)
► The integer value shall be 12'000 if the measurement is 120A

After selecting the measured quantity and entering the register va lue of 12'000 automatically a scaling
factor of 100.0 is calculated. The measurement I1 therefore will be multiplied by 100.0 before it is
converted into an integer value and stored in the Modbus image.

Also in the integer image instantaneous, mean, unbalance or THD/TDD values may be arranged.

For devices with Profibus interface the Modbus image is used for the assembly of the
cyclical telegram. Via Modbus the same image can be used, but it’s not possible to use it
independently.

The Modbus communication of the A

PLUS is described in a separate document. Depending on the

communication hardware selected, either the manual for Modbus/RTU or Modbus/TCP protocol should be
used. These documents can be downloaded via our homepage http://www.camillebauer.com

5.4 Inputs

All voltage measurement inputs must originate at circuit breakers or fuses rated 10 Amps or
less. This does not apply to the neutral connector. You have to provide a method for
manually removing power from the device, such as a clearly labeled circuit breaker or a
fused disconnect switch.

When using voltage transformers you have to ensure that their secondary connections
never will be short-circuited.

No fuse may be connected upstream of the current measurement inputs !
When using current transformers their secondary connectors must be short-circuited

during installation and before removing the device. Never open the secondary circuit under
load.

The connection of the inputs depends on the configured system (connection type). The required device

external fusing of the voltage inputs is not shown in the following connection diagrams.

5.5 Rogowski current inputs

The connection of the Rogowski coils is performed depending on the selected system type, as shown in
chapter 5.4 above. However, instead of current transformers a Rogowski coils is placed around each
current-carrying conductor. This is subsequently shown for the measurement in a 4-wire low-voltage
system.

When connecting the coils you must follow the safety notices given in the operating
instructions of the Rogowski coil. The current direction shown on the coils must match the
real current direction and has to be the same for all phases.

In order to suppress injected interferences
the shielding (green) is connected always to
the l terminal of the current inputs (I1-l, I2-l
resp. I3-l).

22/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

5.6 Power supply

A marked and easily accessible curren t limiting switch has to be arranged in the vicinity of
the device for turning off the power supply. Fusing should be 10 Amps or less and must be
rated for the available voltage and fault current.

5.7 Relays

When the device is switched off the relay contacts are de-energized, but dangerous
voltages may be present.

The relay X2 is part of the basic unit and therefore always available.
The relays X5 and X6 are provided for device versions with I/O
extension PCB only.

The plug-in terminals have different colours to prevent mixing up the
connections. The pin assignment is the same for all relays:

23/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

5.8 Digital inputs and outputs

For the digital inputs / outputs an external power supply of 12 / 24V DC is required.

The power supply shall not exceed 30V DC !

The plug-in terminal X7 is available for device versions with I/O
extension PCB only.

The number of digital inputs / outputs varies depending on the
optional built-in PCB, see nameplate. The operating direction of
the digital I/Os on X7 may be individually selected by means of
the PC software.

The assignment of the connections depends on
whether an I/O is configured to be a digital input or a
digital output.

Example
Device with I/O extension 2 (2 relays + 6 digital I/Os)

The digital I/Os on plug-in terminal X7 are individ ually
programmable as input or output .

On plug-in terminal X3 a digital input and a digital output are
provided statically. Their operating direction may not be
modified.

Usage as digital input

► Meter tariff switching
► Operating feedback of loads for operating time counters
► Trigger and release signal for logic module
► Pulse input for meters of any kind of energy
► Clock synchronization
► Synchronization of billing intervals in accordance with energy provider

Technical data
Input current < 7,0 mA
Counting frequency (S0) ≤ 16 Hz
Logical ZERO - 3 up to + 5 V
Logical ONE 8 up to 30 V

24/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

Usage as digital output

► Alarm output for logic module
► State reporting
► Pulse output to an external counter (acc. EN62053-31)
► Remote controllable state output via bus interface

Driving a relay

Technical data
Rated current 50 mA (60 mA max.)
Switching frequency (S0) ≤ 20 Hz
Leakage current 0,01 mA
Voltage drop < 3 V
Load capacity 400 Ω … 1 MΩ

Driving a counter mechanism

1) Recommended if input
impedance
of counter > 100 kΩ

The width of the energy pulses can be selected by means of the PC
software but have to be adapted to the counter mechanism. Once a
second there is a decision how many pulses have to be output.
Therefore the delay between two pulses may not be used to
determine the present power demand.

Electro mechanical meters typically need a pulse width of

50...100ms.
Electronic meters are partly capable to detect pulses in the kHz

range. There are the types NPN (active negative edge) and PNP
(active positive edge). For the APLUS a PNP type is required. The
pulse width has to be at least 30ms (acc. EN62053-31). The delay
between to pulses corresponds at least to the pulse width. The
smaller the pulse width, the higher the sensitivity to disturbances.

25/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

5.9 Analog outputs

Analog outputs are available for devices with I/O extension 1 only. See nameplate.

Connection to an analog input card of a PLC or a
control system

The A

PLUS is an isolated measurement device. In

addition the particular outputs are galvanically
isolated. To reduce the influence of disturbances
shielded a twisted-pair cables should be used. The
shield should be connected to earth on both opposite
ends. If there a potential differences between the ends
of the cable the shield should be earthed on one side
only to prevent from equalizing currents.

Under all circumstances consider as well appropriate
remarks in the instruction manual of the system to
connect.

5.10 Modbus interface RS485 X4 and / or X8

Depending on the device version up to two Modbus interfaces are available on the plug-in positions X4
and / or X8. These are galvanically isolated. The connection terminals are distinguished by color: X4
(gray), X8 (black).

1) One ground connect ion only . T his
is possibly made within the
master (PC).

Rt: Termination resistors: 120 Ω each

for long cables (> approx. 10 m)

Rs: Bus supply resistors,

390 Ω each

The signal wires (X4-1, X4-2 resp. X8-1, X8-2) have to be twisted. GND (X4-3 resp. X8-3) can be
connected via a wire or via the cable screen. In disturbed environments shielded cables must be used.
Supply resistors (Rs) have to be present in bus master (PC) interface. Stubs should be avoided when
connecting the devices. A pure daisy chain network is ideal.

You may connect up to 32 Modbus devices to each bus. A proper operation requires that all devices
connected to the respective bus have equal communication settings (baud rate, transmission format) and
unique Modbus addresses. If there are two Modbus interfaces, their settings may be different.

The bus system is operated half duplex and may be extended to a maximum length of 1200 m without
repeater.

26/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

5.11 Profibus DP interface

The 9-pin DSUB socket serves the connection of a standard Profibus plug. In a bus terminal device, the
bus line must be terminated with resistors in the bus plug. Then standard pin assignment is as follows:

Pin Name Description

3 B RxD/TxD-P
4 RTS Request to send: CNTR-P (TTL)
5 GND Data groun d
6 +5V VP
8 A RxD/TxD-N

ON Parameterization ok; Profibus communication active

27/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

6. Commissioning

Before commissioning you have to check if the connection data of the transducer match the
data of the plant (see nameplate).

If so, you can start to put the device into operation by switching on the power supply and the
measurement inputs.

6.1 Software installation CB-Manager

A complete parametrization of the device is possible via configuration interface only, using the PC
software CB-Manager. The software may be downloaded free of charge from our homepage

http://www.camillebauer.com

.

The file "Read-me-first" provides all necessary information for the installation of the
CB-Manager software and assistance for possible problems.

Functionality of the CB-Manager software

The software is primary a tool for the configuration of different devices (A

PLUS, CAM, VR660, A200R,

V604s) and supports the user during commissioning and service. It allows as well the reading and
visualization of measured data.

►Acquisition and modification of all device features
►Setting of real-time clock and time zone, selection of time synchronization method
►Archiving of configuration and measurement files
►Visualization of present measurements
►Reading, setting and resetting of meters
►Reading and resetting of minimum/maximum values
►Starting, stopping and resetting of the optional data logger
►Recording of measurement progressions during commissioning
►Check for correct device connection
►Simulation of states or outputs to test subsequent circuits
►Adjust the security system as protection against unauthorized access or manipulations

The CB-Manager software provides a comprehensive help facility, which describes in detail the operation
of the software as well as all possible parameter settings.

28/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

6.2 Parametrization of the device functionality

Operating the software

The device configuration is divided into registers, which contain thematically the different function blocks
of the device, e.g. "input", "limit values", "display". Thereby of course there are interdependencies, which
have to be considered. If e.g. a current limit value is defined and subsequently the ratio of the current
transformer is changed, there is a high probability that the limit value is changed as well. Therefore a
meaningful sequence must be kept during setting the parameters. The easiest way is to handle register
by register and line by line:

► Device (set the device version, if not read directly from the device)

If an I/O extension unit is used: Fix the data direction of the digital I/O's. Do to so just click on the
appropriate entry and change the data direction in the I/O register. So it's assured that these I/O's
can be used in the intended way. If e.g. you miss to change de basic setting "digital input" the
appropriate channel can't be used as output in the logic module.

► Input, especially system and transformer ratios
► Mean values >> Limit values >> Logic module >> I/O 1-3
► if present: I/O 4,5 >> I/O 6,7 >> I/O 8,9 >> I/O 10,11
► Operating hours
► if present: Logger >> Interface (Ethernet, Profibus DP) >> Display
► Modbus-Image (if you want to define your own Modbus image)
► Time zone (for automatical handling of daylight saving time)

29/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

ONLINE / OFFLINE

The parametrization may be performed ONLINE (with existing connection to the device) or OFFLINE
(without connection to the device). To perform an ONLINE configuration first the configuration of the
connected device, and therewith its hardware version, is read. A modified configuration can then be
downloaded to the device and stored on the hard disk of the computer for archiving.

An OFFLINE parametrization can be used to prepare device configurations, to store them on disk and to
download it to the devices, once you are in the field where the devices are installed. To make this work,
the device versions selected during parametrization must agree with the versions on site.

6.3 Installation check

Check if inputs are connected correctly

► Voltage (at least 20% U

rated

) and current (at least 2% I

rated

) must be present

Using the connection check, which is integrated in the visualization of the instantaneous values, the
correct connection of the current and voltage inputs may be checked. The phase sequence will be
checked, as well as if there are open connections or reversed current connections (which change the
direction of the current).

The image below shows open current connections (red description I1, I2, I3). This arises because the
individual currents are below 2% of the rated value.

Simulation of I/O's

To check if subsequent circuits will work properly with the measurement data provided by the A

PLUS all

analog, digital and relay outputs may be simulated, by predefining any output value resp. discrete state by
means of the CB-Manager software.

Also all functions of the logic module, which allows performing any combination of logical states, may be
predefined. This way e.g. an alarming due to a violation of a limit value can be simulated.

30/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

6.4 Installation of Ethernet devices

6.4.1 Connection

Before devices can be connected to an existing Ethernet network, you have to ensure that they
will not disturb the normal network service. The rule is:

None of the devices to connect is allowed to have the same IP address
than another device already installed

The factory setting of the IP address of APLUS is: 192.168.1.101

The standard RJ45 connector serves for direct connecting an Ethernet cable. If the PC is directly
connected to the device a cross-wired cable must be used.

The network installation of the devices is done by means of the CB-Manager software (see 6.4.2

) or
directly via the local programming on the display. As soon as all devices have a unique network address
they may be accessed by means of a suitable Modbus master client.

 Interface: RJ45 connector, Ethernet 100BaseTX
 Mode: 10/100 MBit/s, full / half duplex, Auto-negotiation
 Protocols: Modbus/TCP, NTP

 ON as soon as a network connection exists



LED 2 (Orange)

 Flashing with 4 Hz during start-up

To have a unique identification of Ethernet
devices in a network, to each connection a
unique MAC address is assigned. This
address is given on the nameplate, in the
example 00-12-34-AE-00-01.

Compared to the IP address, which may be
modified by the user any time, the MAC
address is statically.

31/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

6.4.2 Network installation using the CB-Manager software

For the subsequent Modbus/TCP communication a unique network address must be assigned to each of
the devices. This can be done very easily, using the CB-Manager software to search for devices which
have a MAC address 00-12-34-AE-xx-xx, which identifies the device as A

PLUS of Camille Bauer. Because

this is performed by means of a UDP broadcast telegram, the devices are allowed to have the same
network address at the beginning, e.g. "192.168.1.101" as factory default.

As soon as to all the devices network settings with unique IP address have been assigned, they may be
accessed and read using the Modbus/TCP protocol.

Select "settings" under options
| interface. The interface type
has to be set to "TCP-IP".

Devices in the local network

Set settings to "CAM, APLUS".
Along with all A

PLUS also

SINEAX CAM devices installed
in the same network will be
shown. The identification of the
devices is possible by means
of their MAC address, which is
given on the nameplate (see

chapter 6.4.1

).

To assign a unique network
address to a device, select it in
the list and the click on
"change".

The following settings have to be arranged with the
network administrator:

- IP address: This one must be unique, i.e. ma y be
assigned in the network only once.

- Subnet mask: Defines how many devices are
directly addressable in the network . This setting is
equal for all the devices.

- Default gateway: Is used to resolve addresses
during communication between different networks.
Should contain a valid address within the own
network.

- Hostname: Individual designation for each device.
Helps to identify the device in the device list.

32/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

Example

MAC

00-12-34-AE-00-01 00-12-34-AE-00-04 00-12-34-AE-00-07

Devices outside the local network

Devices which are not in the same network as the PC (e.g. in the Internet) can not be found and have to
be added manually to the device list by means of

. The type of the device must be selected previously.
To each entry you have to assign a unique IP and MAC address, which are different from the initial value.
Otherwise it's not possible to add further entries.
The setting of the network parameters must be performed before mounting the device. As an alternative
this may be done in the destination network via Ethernet interface.

6.4.3 Network installation by means of local programming

The network settings IP address, subnet mask and gateway can also be configured directly via the local
programming of the A

PLUS on site.

This facility is shown in chapter 7.8

33/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

6.4.4 Time synchronization via NTP-protocol

For the time synchronization via Ethernet NTP (Network Time Protocol) is the standard. Corresponding
time servers are used in computer networks, but are also available for free via Internet. Using NTP it's
possible to hold all devices on a common time base.

Two different NTP servers may be defined. If the first server is not available the second server is used for
trying to synchronize the time. Adjusting of the clock is performed in the interval selected (15min. up to
24h). If no time synchronization is desired, to both NTP servers the address 0.0.0.0 have to be assigned.

The setting of the addresses is done by means of the CB-Manager software. The NTP data is arranged in
the register "Ethernet" of the device configuration.

Activation

To activate the time synchronization via NTP, the "Synchronisation RTC" must be checked by means of
the checkbox.

6.4.5 TCP ports for data transmission
TCP ports

The TCP communication is done via so-called ports. The number of the used port allows determining the
type of communication. As a standard Modbus/TCP communication is performed via TCP port 502, NTP
uses port 123. However, the port for the Modbus/TCP telegrams may be modified. You may provide a
unique port to each of the devices, e.g. 503, 504, 505 etc., for an easier analysis of the telegram traffic.
The setting of the Modbus TCP port is done as shown above. Independent of these setting a
communication via port 502 is always supported. The device allows at least 5 connections to different
clients at the same time.

Firewall

Due to security reasons nowadays each network is protected by means of a firewall. When configuring the
firewall you have to decide which communication is desired and which have to be blocked. The TCP port
502 for the Modbus/TCP communication normally is considered to be unsafe and is very often disabled.
This may lead to a situation where no communication between networks (e.g. via Internet) is possible.

34/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

6.5 Installation of Profibus DP devices

The Profibus DP interface allows data exchange with a control system via Profibus-DP V0. The modular
device model provides maximum protocol efficiency.

Required measured variables are determined during engineering and arranged as a fixed process image.
The control system does not require any intelligence for the evaluation of the data (no tunneling protocol).

Bus parameterising facilitates simple and fast commissioning. On-site the parameters in accordance wit h
the configuration menu

can be set, especially:

- Device address

- Accepting master parameterization (Check_User_Prm)

- Establishing communication to the master (Go_Online)

- Setting device address via master (Set_Slave_Addr_Supp)

For the assembly of the cyclical Profibus telegram the Modbus image is used. Via Modbus
the same image can be used, but it’s no longer possible to use it independently.

GSD parameterization

Typically the parameterization of the Profibus slave is done on the control system. During startup the
A

PLUS adopts these settings. Doing so the parameterization of the input parameters (input system,

transformer ratios etc.) as well as the assembly of the Modbus image will be overwritten. Other parts of
the configuration, such as parameterization of I/O’s or settings of limit values, remain unchanged.

All necessary informations for the parameterization are part of the DMF (GSD) file. This one can be
downloaded from our homepage http://www.camillebauer.com

.

The assumption of the engineered parameters can be prevented by deactivating the Check_User_Prm
flag. The parameterization locally set will not be changed this way.

Cyclical data exchange

The user can compose its own „station“ with all required quantities. Up to 60 measured quantities can be
modularly concatenated. You may choose from instantaneous values of the system and imbalance
analysis, mean-values of power quantities and freely selectable quantities as well as meter values.

Subsequent to the adoption of the parameterization, the A

PLUS is ready for the cyclical data exchange with

the control system.

6.6 Protection against device data changing

Data stored in the device may be modified or reset via communication interface or via the keys on the
device itself. To restrict these possibilities on-s it e , via CB-Manager the security system in the device can
be activated (factory default: not activated). For the definition of these user rights in the software the input
of an administrator login is required. The factory default is:

user: admin
password: admin

The administrator password may be modified, but a
reset can be performed in our factory only !

For one user via device and one user via interface (special login) the access to the following functions can
individually be granted: Configuration of the device, modification of RTC parameters, modification of limit
values, reset of min/max or meter values, alarm acknowledgment, display mode changing.

7.2 Operating modes
The device supports, along with the configuration mode, three different operating modes. Normally the

device is in the measurement display mode, but may be temporarily switched for the reading of the meters
or for the display of alarm texts.

Measurement display

: Is the normal operating mode of the

device. By means of the navigation keys different measurement
display can be selected. Depending on the selected display mode
and the system monitored different measurement displays are
available.

► Available display modes

Meter reading

: By pressing the key for a longer time an
operating mode is started, which allows to read all the meter
contents via line 4. This mode is automatically stopped after 30s
without any key pressed or via the key . If this mode is active
no measurement info is displayed on line 1 to 3.

► Meter reading

Alarm display

: By shortly pressing the key an operating
mode is started, which allows to display alarm state texts and to
acknowledge alarms via line 4. If there are no configured alarms
the message "No LED used" is displayed and then the mode is
stopped. Otherwise the mode is automatically stopped after 30s
without any key pressed or via the key . If this mode is active
no measurement info is displayed on line 1 to.

Brighter: Press key longer than 2s; brightness will increase in steps
Darker: Press key longer than 2s; brightnes s w ill dec reas e in ste ps

39/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

7.4 Display modes

The device supports four different display modes. They differ in the way measurement data is presented

and which measurement data is provided.

► The selection of the display mode is described under Configuration

FULL mode

The measurement images of all displayable data are arranged in a matrix form. The selection is

performed by means of the arrow keys:

One image to the left. If first: most right image is displayed
Most left image of the next line is displayed. If last: First line.
Most left image of the previous line is displayed. If first: Last line.
One image to the right. If last: most left image is displayed

The fourth line of each image is allocated to a programmable meter value (METER), which does not
change even if another measurement image is selected.

REDUCED mode

This display mode is a reduced version of the FULL mode. Some of the images or complete lines, e.g. the

grayed data in the below example, can be hidden. So the display may be adapted easily to the
information requirements on-site.

The selection of the measurement images is done via the arrow keys:

One image to the left. If first: most right image is displayed
Most left image of the next line is displayed. If last: First line.
Most left image of the previous line is displayed. If first: Last line.
One image to the right. If last: most left image is displayed

The fourth line of each image is allocated to a programmable meter value (METER), which does not
change even if another measurement image is selected.

USER mode

This display mode allows a free assembly of up to 20 measurement images. Also the fourth line may be

different for each image. Any meter value or another quantity (Ux, Ix, Px, Qx, Sx) may be assigned. The
images are arranged among each other and selectable via the keys and :

Image of the next line is displayed. If last: First line.
Image of the previous line is displayed. If first: Last line.

The USER mode also allows defining one of the 20 measurement images to be a predefined image,

which is displayed always after a programmable time without user action. This switch back is performed
even if in the meantime a change to the FULL or REDUCED mode was performed. This way an always
equal appearance of the device can be defined in advance.

display mode. When a meter content is displayed it may be reset to zero

if the necessary rights have been

granted during the configuration of the device.

Start reading: Press key longer than 2s;

Stop reading: Press key ;

► The first displayed meter is always active energy incoming, high tariff
► Using the keys and other values from the list of meters may be read as well

After a time of 30s with no key pressed the meter reading is automatically stopped !

43/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

7.6 Alarm handling

How alarms are handled is fixed during the configuration of the device. A detailed description about the
alarming concept is here:

► Monitoring und alarming

7.6.1 Alarm state display on the device

The yellow state LED's are intended for alarming and alarm state display on-site. The displayed states are
the result of the state information analysis, defined by the user in the logic module. The type of signaling
is comparable to the operating philosophy in control rooms.

LED Meaning
OFF Alarm is not active
ON Alarm is active and acknowledged
Fast FLASHING 1)

Alarm is active but not yet acknowledged

Slow FLASHING 1)

Alarm was temporarily active and not yet acknowledged

1)

If "acknowledgement of alarm LEDs required" in the logic module configuration is not

selected flashing is omitted.

The status display of the LED's is performed only, if the associated logic functions
have been configured accordingly

7.6.2 Display of alarm texts

The displayed alarm texts are the result of the state information analysis, defined by the user in the logic
module. The number of entries in the alarm text list depends on how many logic functions are used. If no
function is used, when changing to the alarm display mode an appropriate error message is displayed and
then the mode is terminated immediately. If logic functions are defined, the alarm list may contain up to
four entries.

To each alarm a state text for the active and the inactive state
is assigned. The table of the present alarm state texts contains,
depending on the present state, either the text for the active or
the inactive alarm. These may be retrieved and displayed on
line 4. The first displayed alarm text after starting the alarm text
display is the one with the highest priority (see flow diagram,
next page).

Start alarm text display: Press shortly;

Stop alarm text display: Press key ;

After a time of 30s with no key pressed the display of alarm texts is automatically stopped !

44/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

7.6.3 Acknowledgment of alarms via display

Acknowledgment is not required if "acknowledgement of alarm LEDs required" in the
logic module configuration is not selected.

The acknowledgment of alarms may be performed via the keys on the device. To do so, the alarm to
acknowledge must be actually displayed.

ACKNOWLEDGMENT: Press key (longer than 2s);

LED before acknowledgment LED after acknowledgment
#C: Fast FLASHING #B: ON
#D: Slow FLASHING #A: OFF

If the display is configured for alarm reset, the acknowledgment also undoes the possible
alarm operation (e.g. the switching of a relay).

45/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

7.7 Resetting of measurements

The APLUS provides minimum and maximum values of different measured quantities as well as energy
meters and operating hour counters. All of them may be reset during operation.

Basic principle

RESET: Press key (longer than 2s) while the quantity to reset is displayed

Setting time and date

All time information stored in the device is referenced to UTC

1)

(Universal Time Coordinated). For a better
understanding the time/date information displayed on the display can be converted to local time by
defining a time zone offset. This offset is added to the internal UTC time before the time information is
displayed. Keep in mind that the offset may be variable if daylight saving time is used locally (see below).

Hint: If time is set via CB-Manager software the difference between local time and UTC rather results
from the local time settings of the PC than from the time zone offset configured via display. There may be
a discrepancy.

Sometimes UTC is called world time as well. The reference corresponds to the Greenwich Mean Time
(GMT). The time zones of the world nowadays are all referenced with an offset to UTC. UTC time doesn't
use time shifts, which may occur due to a change to daylight saving time.

Example: In Switzerland the CET (Central European Time) is valid, which has an offset of +1[h] to UTC.
But during half of the year the CEST (Central European Summer Time) is used, which has an offset of
+2[h] to the UTC time used in the device.

7.8.1 Selection of the parameter to edit

To modify a value you have to navigate through the menu tree by means of the arrow keys until the

appropriate parameter is displayed. For the parameter selected on line 4 a detailed description is

By configuring the different data loggers their state will not be changed. If it was active it remains active, if
it was inactive it remains inactive. The activation / deactivation of a specific logger may be performed via
PC software or via the local programming menu

. Only via PC software, respectively by using the

corresponding commands via the configuration interface, contents of the individual logger can be reset.
Lists are exceptional, because they are always active to prevent manipulations. They record events in

endless mode and can’t be reset.

7.9.2 SD card

The device is supplied with a 2 GByte SD card, which allows long-term recodings. The device can be
equipped with all other SD cards available.

The red LED of the key located next to the SD card
signalizes that the logger is active. During writing to the
card the LED becomes dark for a short time.

To exchange an SD card the key must be pressed. As
soon as the red LED becomes dark, the SD card can
be removed and the new card inserted. Data can’t be
latched in the device. Therefore there is no recording
for the time no card is present in the device.

Status messages on LED display

7.9.3 Access to logger data

Only for device versions with Ethernet a direct access tot he logger data via interface is possible. For all
other versions you have to remove the SD card first and to access the recorded data using an internal or
external card reader. The analysis of the data is performed using the CB-Analyzer software.

7.9.4 Logger data analysis

The analysis of recorded logger data can be done using the PC software CB-Analyzer. The software may
be downloaded free of charge from our homepage http://www.camillebauer.com

.

The file "Read-me-first" provides all necessary information for the installation of the
CB-Analyzer software and assistance for possible problems.

Functionality of the CB-Analyzer software

This .NET-based software facilitates the data acquisition and analysis of the optional data loggers and
lists of SINEAX CAM and A

PLUS. The data read from the devices will be stored in a database. The

program is capable of processing several devices simultaneously.

► Acquisition of logger and list data of several devices
► Storage of the data in a database (Access, SQLClient)
► Different analyzing options of the acquired data, also across devices
► Report generation in list or graphic format
► Selectable time range in the preparation of reports
► Export of report data to Excel or as an Acrobat PDF file

The CB-Analyzer software provides a comprehensive help facility, which describes in detail the operation
of the software. Below a screen-shot is shown, which shows as an example the graphical analysis of the
power demand of a factory over one week.

of device data.

► Protection against device data modifications

8.2 Calibration and new adjustment

Each device is adjusted and checked before delivery. The condition as supplied to the customer is
measured and stored in electronic form.

The uncertainty of measurement devices may be altered during normal operation if, for example, the
specified ambient conditions are not met. If desired, in our factory a calibration can be performed,
including a new adjustment if necessary, to assure the accuracy of the device.

8.3 Cleaning

The display and the operating keys should be cleaned in regular intervalls. Use a dry or slightly moist
cloth for this.

Damage due to detergents

Detergents may not only affect the clearness of the display but also can damage the device.
Therefore, do not use detergents.

8.4 Battery

The device contains a battery for buffering the internal clock. It cannot be changed by the user. The
replacement can be done at the factory only.

Power factors

The power facto r PF gives the relation

between active and apparent power. If
there are no harmonics present in the
system, it corresponds to the cosφ (see
also

Reactive power). The PF has a

range of -1...0...+1, where the sign gives
the direction of energy flow.

The load factor LF is a quantity derived
from the PF, which allows making a
statement about the load type. Only this
way it's possible to measure a range like

0.5 capacitive ... 1 ... 0.5 inductive in a
non-ambiguous way.

The reactive power factor QF gives the
relation between reactive and apparent
power.

Zero displacement voltage UNE

Starting from the generating system with star point E
(which is normally earthed), the star point (N) on load
side is shifted in case of unbalanced load. The zero
displacement voltage between E und N may be
determined by a vectorial addition of the voltage vectors
of the three phases:

UNE = - (U1N + U2N + U3N ) / 3

A displacement voltage may also occur due to
harmonics of order 3, 9, 15, 21 etc., because the
dedicated currents add in the neutral wire.

Earth fault monitoring in IT systems

Via the determination of the zero displacement voltage it's possible to detect a first earth fault in an

unearthed IT system. To do so, the device is configured for measurement in a 4-wire system with
unbalanced load and the neutral connector is connected to earth. In case of a single phase earth fault
there is a resulting zero displacement voltage of U

LL

/ √3. The alarming may be done e.g. by means of a

relay output.

Transformer, secondary side Load

Because in case of a fault the voltage triangle formed by the three phases does not change the voltage

and current measurements as well as the system power values will be still measured and displayed

correctly. Also the meters carry on to work as expected.

The method is suited to detect a fault condition during normal operation. A declination of the isolation

resistance may not be detected this way. This should be measured during a periodical control of the system

using a mobile system.

Another possibility to analyze fault conditions in a grid offers the method of the symmetrical components

as

described in A3.

Harmonics

Harmonics are multiple of the fundamental resp. system frequency. They arise if non-linear loads, such as
RPM regulated drives, rectifiers, thyristor controlled systems or fluorescent lamps are present in the
power system. Thus undesired side effects occur, such as additional thermical stress to operational
resources or electrical mains, which lead to an advanced aging or even damage. Also the reliability of
sensitive loads can be affected and unexplainable disturbances may occur. In industrial networks the
image of the harmonics gives good information about the kind of loads connected. See also:

► Increase of reactive power due to harmonic currents

TDD (Total Demand Distortion)

In the A

PLUS the complete harmonic content of the currents is shown as Total Demand Distortion, briefly

TDD. This value is scaled to the rated current resp. rated power. Only this way it's possible to estimate the
influence of the current harmonics on the connected equipment correctly.

Maximum values

The maximum values of the harmonic analysis arise from the monitoring of THD and TDD. The maximum
values of individual harmonics are not monitored separately, but are stored if a maximum value of THD or
TDD is detected. The image of the maximum harmonics therefore always corresponds to the dedicated
THD resp. TDD.

The accuracy of the harmonic analysis depends strongly on the quality of the current and voltage
transformers possibly used. In the harmonics range transformers normally change both, the
amplitude and the phase of the signals to measure. It's valid: The higher the frequency of the
harmonic, the higher its damping resp. phase shift.

Available via interface only

Imbalance in three-phase systems may occur due to single-phase loads, but also due to failures, such as

e.g. the blowing of a fuse, an earth fault, a phase failure or an isolation defect. Also harmonics of the 3rd,

9th, 15th, 21st etc. order, which add in the neutral wire, may lead to imbalance. Operating resources

dimensioned to rated values, such as three-phase generators, transformers or motors on load side, may

be excessively stressed by imbalance. So a shorter life cycle, a damage or failure due to thermical stress

can result. Therefore monitoring imbalance helps to reduce the costs for maintenance and extends the

undisturbed operating time of the used resources.

Imbalance or unbalanced load relays use different measurement principles. One of them is the approach

of the symmetrical components, the other one calculates the maximum deviation from the mean-value of

the three phase values. The results of these methods are not equal and don't have the same intention.

Both of these principles are implemented in the A

PLUS.

Symmetrical components (acc. Fortescue)

The imbalance calculation method by means of the symmetrical components is ambitious and intensive to

calculate. The results may be used for disturbance analysis and for protection purposes in three-phase

systems. The real existing system is divided in symmetrical system parts: A positive sequence, a negative

sequence and (for systems with neutral conductor) a zero sequence system. The approach is easiest to

understand for rotating machines. The positive sequence represents a positive rotating field, the negative

sequence a negative (braking) rotating field with opposite sense of direction. Therefore the negative

sequence prevents that the machine can generate the full turning moment. For e.g. generators the

maximum permissible current imbalance is typically limited to a value of 8...12%.

Maximum deviation from the mean value

The calculation of the maximum deviation from the mean value of the phase currents resp. phase

voltages gives the information if a grid or substation is imbalanced loaded. The results are independent of

rated values and the present load situation. So a more symmetrical system can be aspired, e.g. by

changing loads from one phase to another.

Also failure detection is possible. The capacitors used in compensation systems are wear parts, which fail

quite often and then have to be replaced. When using three phase power capacitors all phases will be

compensated equally which leads to almost identical currents flowing through the capacitors, if the system

load is comparable. By monitoring the current imbalance it's then possible to estimate if a capacitor failure

is present.

The maximum deviations are calculated in the same steps as the instantaneous values and therefore are

Most of the loads consume a combination of ohmic and inductive current from the power system. Reactive
power arises by means of the inductive load. But the number of non-linear loads, such as RPM regulated
drives, rectifiers, thyristor controlled systems or fluorescent lamps, is increasing. They cause non­sinusoidal AC currents, which may be represented as a sum of harmonics. Thus the reactive power to
transmit increases and leads to higher transmission losses und higher energy costs. This part of the
reactive power is called distortion reactive power.

Normally reactive power is unwanted, because there is no usable active component in it. Because the
transmission of reactive power over long distances is uneconomic, it makes sense to install compensation
systems close to the consumers. So transmission capacities may be used better and losses and voltage
drops by means of harmonic currents can be avoided.

P: Active power
S: Apparent power including

harmonic components
S1: Fundamental apparent power
Q: Total reactive power
QG: Fundamental reactive power
D: Distortion reactive power

68/89 Device handbook APLUS with / without LED display, 157 679-19, 04/2016

The reactive power may be divided in a fundamental and a distortion component. Only the fundamental
reactive power may be compensated directly by means of the classical capacitive method. The distortion
components have to be combated using inductors or active harmonic conditioners.

The A

PLUS reports a load factor PF which is the relation between active power P and apparent power S,

including all possibly existing harmonic parts. This factor is often called cosφ, which is only partly correct.
The PF corresponds to the cosφ only, if there is no harmonic content present in the system. So the cosφ
represents the relation between the active power P and the fundamental apparent power S1.

Also calculated is the tanφ, which is especially known as a target quantity for the reactive power
compensative using capacitors. It corresponds to the relation of the fundamental reactive po wer QG and
the active power P. Here intentionally the fundamental reactive power is used for the calculation, because
this is the only component which may be directly compensated via capacitors.

Available via interface only 1) Interval time t1 2) Interval time t2

The device calculates automatically the mean values of all system power quantities. In addition up to 12

further mean value quantities can be freely selected.

Calculating the mean-values

The mean value calculation is performed via integration of the measured instantaneous va lues ov er a
configurable averaging inte r val. The interval time may be selected in the range from one second up to one
hour. Possible interim values are set the w a y that a multiple of it is equal to a minute or an hour. Mean
values of power quantities (interval time t1) and free quantities (interval time t2) may have different
averaging intervals.

Synchronization

For the synchronization of the averaging intervals the internal clock or an external signal via digital input
may be used. In case of an external synchronization the interval should be within the given range of one
second up to one hour. The synchronization is important for making e.g. the mean value of power
quantities on generating and demand side comparable.

Trend

The estimated final value (trend) of mean values is determined by weighted addition of measurements of

the past and the present interval. It serves for early detection of a possible exceeding of a given maximum
value. This can then be avoided, e.g. by switching off an active load.

History

For mean values of system powers the last 5 interval values may be displayed on the device or read via

interface. For configurable quantities the value of the last interval is provided via communication interface.
